The ABC of DNA Computing

5. Using complementarity to link connecting flights.

In the experiment, strands representing the flights are mixed in a test-tube with the complements to the strands representing the airports. If we let Atlanta* represent the complementary strand, etc., this gives

Atlanta

Atlanta*

Dallas

Dallas*

Chicago

Chicago*

The test-tube then holds

Atlanta*

Atl->Dal

Dallas*

Atl->Chi

Chicago*

Dal->Chi

etc.

Chi->Dal

etc.

When the contents are mixed, complementary sections of strand will bond,yielding products of reaction like:
